What is a Refraction?

A refraction is part of the eye exam that tells the doctor what eyeglass prescription will help you see better. A new eyeglass prescription is one by-product of a refraction. The refraction is a critical part of any eye examination. It also helps us determine whether one’s vision is reduced by an eye disease (cataracts, macular degeneration, etc.) or some other problem. It helps us to follow the progression of cataracts and many other processes. The refraction is what helps us to better diagnose and manage the patient’s condition, it’s not just for an eyeglass prescription. However, it is the part of the eye exam that Medicare does not cover and if you have Medicare, you will be asked to pay the refraction fee.
